Moistening machine for wallpaper



patented Oct. 4, 1949 UNITED STATES ATENT' OFFICE 5 Claims.

This invention relates to new and useful improvements and structural refinements in moistening machines, and the principal object of the invention is to provide a device of the character herein described, such as may be conveniently and effectively employed for the applying of adhesive paste to wall paper, preparatory to the positioning of the paper upon the wall.

A further object of the invention is to provide a moistening machine through which the paper may be easily and conveniently fed.

Another object of the invention is to provide a moistening machine which is of an easily portable nature and which may be positioned adjacent the base-board of the wall, in readiness for convenient use.

An additional object of the invention is to provide a moistening machine which is simple in construction and operation, and which will not easily become damaged.

A still further object of the invention is to provide a moistening machine which may be readily dismantled for purposes of cleaning, inspection or repairs.

With the above more important objects in view and such other objects as may become apparent as this specification proceeds, the invention consists essentially of the construction and arrangement of parts as shown in the accompanying drawings in which:

Figure 1 is a top plan view of the invention,

Figure 2 is a cross-sectional view, taken substantially in the plane of the line 2-2 in Figure 1, and

Figure 3 is a side elevational view, showing the invention when not in use.

Like characters of reference are used to designate like parts in the specification and throughout the several Views.

Referring now to the accompanying drawings in detail, the invention consists of a moistening machine designated generally by the reference character 5, the same embodying in its construction a substantially rectangular tank 6, provided with sloping end walls 1 and adapted to hold a 1 uid paste 8, while the roller l 5 is positioned somewhat above the liquid level, as is best shown in Figure 2.

A frame designated generally by the reference character I! consists of a pair of spaced parallel side members 18, these being connected together by a cross member l9 assuming the form of an elongated, double angled bracket. A plurality of shafts 20 are rotatably journaled in the side members I 8 of the frame 11, said shafts being retained in position by means of suitable collars Z l These shafts, in effect, assume the form of guide rollers, and will be hereinafter referred to as such.

The frame ll, together with the associated rollers 29 is adapted for mounting upon the tank 6, for which purpose the side walls 9 of the tank are formed with further slots 22, constituting what may be referred to as seats, for the end portions of the shafts 20. Suitable keeper pins 23 are passed through the side walls 9 to engage the side members NS, for the purpose of removably retaining the frame I! in position on the tank.

A substantially fiat clamping bar 24 is adjustably secured medially of its length to the aforementioned cross-member H] by means of a bolt and wing nut designated collectively by the reference character 25. The purposeof the bar 24 will be hereinafter more fully explained.

A pair of upright straps 25 are secured by means of suitable screws '2'! to the end of the tank 6 adjacent the roller l4, said straps being formed atthe upper end thereof with open slots 28 and constituting a yoke for removably and rotatably receiving a feed rod 29. A roll of wallpaper 30 is positioned on this red the paper passing under the adjacent of the rollers 20, over the roller l4, under the intermediate of the rollers 29, over the roller l5, and hence, under the remaining of the rollers 20, as indicated at 3| in the accompanying Figures 1 and 2. I

When the invention is placed in use, the paper is drawn through the machine in the manner already explained, and it should be understood that the machine may be positioned adjacent the base-board'of the wall (not shown), so that the paper which emerges from the machine as at 32 may be applied directly to the wall. During the passage of paper through the machine, the roller M will apply a coating of liquid paste to the undersurface of the paper and the roller IE will effectively spread the paste, so that it is evenly distributed. The rollers 20 act as effective guides for maintaining the paper in proper engagement with the rollers l4, [5.

It should be understood that the roll 30 to 3 gether with the shaft 29 is freely rotatable in the yoke straps 26, so that the paper may be unwound therefrom as desired.

When the invention is not being used, the strap 24, which heretofore has been aligned with the cross-member I9 as shown in Figures 1 and 2, is adjusted so as to engage the paper passing over the roller l4, 15, as shown in Figure 3. By tightening the bolt and nut assembly 25, the friction of the strap 24 upon the paper will effectively prevent the same from unwinding. To facilitate convenient transportation, the side wall 9 of the tank 6 may be provided with suitable handles 33, and it will be also noted that while the machine is being transported, the strap 24 will effectively 1' retain the roller l4 and I5 in the respective slots l0 and H and, thereby prevent the same from rising and falling in the slots.

The machine may be readily disassembled for purposes of cleaning, or for the threading of paper under and over the several rollers, by simply removing the keeper pins 23 and lifting the frame ll, together with the associated rollers 29, from the tank. Thereupon, the paper may be simply laid upon the rollers l4, l5, and the frame ll subsequently dropped into position. It will be also noted that when the frame H is removed from the tank, the rollers I l, l5 may be lifted upwardly from their respective slots 19 and ii,

for the purpose of cleaning and refilling the tank with liquid paste.

It is believed that the advantages and use of the invention will be clearly understood from the foregoing disclosure and accordingly, further description thereof at this point is considered unnecessary.

' While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention claimed.

, What I claim as my invention is:

1. A moistening machine for strip paper comprising a tank having a normal liquid level, a moistening roller rotatably carried by the tank partially disposed below the normal liquid level of the tank, a moisture spreading roller rotatably carried by the tank disposed above the normal liquid level of the tank and spaced parallel to the moistening roller, a plurality of guide rollers car- 4 said moisture spreading roller are tangent to a plane parallel to the liquid level of the tank.

3. A moistening machine for strip paper comprising a tank having a normal liquid level, a moistening roller rotatably carried by the tank having a lower periphery disposed below the liquid level of the tank, a moisture spreading roller rotatably carried by the tank having its entire surface disposed above the liquid level in the tank, the upper surfaces of said rollers being tangent to a plane spaced parallel to the liquid level of the tank, a, plurality of guide rollers carried by the tank under which a strip of paper is trained to frictionally bear upon the moistening roller and moisture spreading roller, the lower surfaces of said guide rollers being tangent to a plane spaced downwardly from and parallel to a plane tangent to the upper surfaces of the moistening roller and moisture spreading roller, and means adjustably carried by the tank and extending transversely between and above the moistening roller and the moisture spreading roller for urging a strip of paper against the moistening roller and the moisture spreading roller.
